Securing a Classroom Door in a Lockdown: Evaluating Two Types of Door Locks

While schools face a variety of security threats, none draw the attention of the community quite like an active shooter event. In fact, following an active shooter event in a school many states, local governments, and/or school districts will announce proposed security measures to better protect students, staff, and visitors to schools. While there are innovated security measures proposed, it is well-known that no shooter has breached a locked door. For this reason, this paper seeks to examine the efficacy of a simple security measure that could have an immediate impact on improving survivability during lockdown procedures – the type of door lock. Specifically, this paper examines two different types of door locks utilizing a randomized control trial. This research effort finds that simple, push-button door locks can be secured with fewer errors and faster than a door lock that requires a key.
